Projects
Twitch Stream Assistant
Python bot that listens and responds to Twitch chat commands in real time. Built a full OAuth2 flow from scratch — app tokens, user access tokens, and automatic refresh — using async HTTP. No library handling it for me.

Personal URL Shortener
Self-hosted URL shortener built for actual personal use. Takes a long URL, generates a short code, and persists the mapping to PostgreSQL via SQLAlchemy. Deliberately minimal — clean API design, easy to extend.

SpaCy NER Explorer
NLP tool that runs Named Entity Recognition across 38,000 CNN news articles (2011–2022). Uses SpaCy's displaCy visualizer to highlight entities and labels in context. Streamlit front-end makes it browser-accessible.
